the supposed 60fps holy grail is based on how much smoother it looks and how many more packets you're sending a server in a multiplayer game than the person using the stock 30fps, since quite often the packet sending rate and maxfps are tied to each other.
Actually, the packets are not tied to the target framerate at all. Not in any game since and including Quake 1, at the very least. The lockstep multiplayer scheme is highly flawed, and is only used in some online RTS games nowadays.
When you play your favorite FPS, i.e. COD4 or Quake Wars online, even if you get 250fps, the rate at which they send and receive data remains something like 15-20pps (packets per second).
The rest is done by movement interpolation routines.
The humans are fooled because there's a profound difference between how many frames you can spot with your eye, and how fast you can react to an event. Just because you can tell 40fps from 50fps doesn't mean that it won't take you 1/5th of a second to acknowledge and consciously react to something happening. If you're good.
